This comprehensive discussion with Professor Bart K explores the carnivore diet, the role of carbohydrates, the Randall cycle, insulin resistance, and the importance of fat. It debunks common myths about carbs, LDL, and metabolic flexibility, offering insights into how to approach a carnivore lifestyle effectively and healthily.
In a recent in-depth conversation, Professor Bart K, a former academic with over 20 years of experience in health science, shared his insights on the carnivore diet, carbohydrates, and metabolic health. This article distills the key points from that discussion, providing a comprehensive understanding of why some carnivores are incorporating carbs again and the scientific reasoning behind it.
Professor Bart K has an extensive background in health science, having taught physiology, human nutrition, and cardiovascular pathophysiology across 11 universities on four continents. Disillusioned with the current state of academia, he transitioned to social media influencing, farming, consulting, and marketing, focusing on health and nutrition.
Many people following a carnivore diet consume 95-99% animal-based foods but occasionally include some carbohydrates. Professor Bart K acknowledges that while this is a significant improvement over the standard Western diet, ideally, one should avoid carbohydrates altogether.
Professor Bart K emphasizes that humans do not require any exogenous carbohydrates. The body can produce all the glucose it needs through gluconeogenesis from non-carbohydrate precursors such as glycerol, lactate, and certain amino acids.
The host shared her journey from veganism to a carnivore diet, noting significant health improvements, including regular and painless menstrual cycles. Professor Bart K cited examples of individuals like Maggie the rancher and Rick Rodriguez, who have thrived on a carnivore diet for decades.
Professor Bart K criticizes the current state of human nutrition science, labeling it as theology and propaganda rather than true science. He points out the absence of conclusive evidence linking dietary interventions to hard health outcomes, making anecdotes the primary source of information.
The Randall cycle (also known as the Randle cycle or TCA cycle) describes the metabolic conflict when fats and carbohydrates are consumed together:
Contrary to popular belief, insulin resistance is a protective mechanism activated by the Randall cycle to prevent cells from taking in excess glucose and suffering glycation damage. It is a result of diabetes, not the cause.
The concept of metabolic flexibility (switching between burning carbs and fats) is often misunderstood and used as marketing propaganda. Humans do not need dietary carbohydrates to function, even athletes. The body can produce all necessary glucose internally.
Professor Bart K encourages a species-appropriate diet focused on animal-based foods, emphasizing the importance of fat for energy and nutrient absorption. He invites open scientific debate and provides resources for further learning.
For those interested in exploring the carnivore diet and understanding the science behind it, Professor Bart K's content offers a wealth of information and a critical perspective on mainstream nutrition science.
